Goals are rare enough that a few bounces can make a good team look bad for weeks. Expected goalsfix that: every shot is scored by how often that exact look — that spot, that angle, that kind of shot — actually goes in. Add them up and you get what a club's chances were worth.

So the two goals rows say what happened, and the two expected-goals rows say what usually happens from those chances. When a club's real goals sit well below its expected goals, it is normally finishing or goaltending — and both tend to drift back toward normal.

Share rows are a slice of the game: 50% is dead even, and anything past about 52% is a club that genuinely tilts the ice.
